  1. 1. Experimental study of the temperature profile in an iron ore pellet during reduction using hydrogen gas

    University essay from KTH/Materialvetenskap

    Author : Julia Brännberg Fogelström; [2020]
    Keywords : Iron ore; Iron oxide; Hematite pellet; Hydrogen reduction; Reduction; Intraparticle temperature; Temperature effect; Temperature profile; Järnmalm; Järnoxid; Hematitpellet; Vätgasreduktion; Reduktion; Invändig temperatur; Temperatureffekt; Temperaturprofil;

    Abstract : We are facing an important challenge, to reduce the greenhouse gas emissions to make sure that we limit global warming to 2 °C, preferably 1.5 °C. Drastic changes and developing new methods may be our only chance to keep global warming under 1.5 °C. READ MORE

  2. 2. Tesla Valve for Hydrogen Decompression: Fluid Dynamic Analysis

    University essay from KTH/Skolan för industriell teknik och management (ITM); KTH/Skolan för industriell teknik och management (ITM)

    Abstract : Människans påverkan på växthuseffekten har under de senaste åren varit en mycket aktuell fråga. Det är många olika faktorer som bidrar till ett negativt avtryck på miljön, där ett stort bidrag kommer från sektorn bilindustri. Majoriteten av dagens bilar drivs på fossila bränslen som genererar skadande utsläpp på miljön. READ MORE

  3. 3. Artificial photosynthesis - 4-Aminobenzoic acids effect on charge transfer in a photo catalytic system

    University essay from Uppsala universitet/Materialteori

    Author : Simon Moberg; [2019]
    Keywords : artificial photosynthesis; aminobenzoic acid; charge transfer; plasmon; induced; plasmon induced; nanostructure; nanostructures; solar energy; nano particles; nano particle; artificiell fotosyntes; aminobensoesyra; laddningsöverföring; plasmon; inducerad; plasmoninducerad; nanostruktur; nanostrukturer; solenergi; nanopartiklar; nanopartikel;

    Abstract : Artificial photosynthesis is used to harvest solar energy and store it in the form of chemical bonds. The system of interest in this study does this by splitting water into hydrogen and oxygen gas through a plasmon assisted process, collective oscillations from free electron gas. READ MORE

  4. 4. Investigation into Melting Characteristics of Hydrogen-Reduced Iron Ore Pellets

    University essay from KTH/Materialvetenskap

    Author : Hedda Pousette; [2019]
    Keywords : Iron Ore Pellets; Sulphur; Phosphorous; Slag; Hydrogen Gas; Järnmalmspellets; Svavel; Fosfor; Slagg; Vätgas;

    Abstract : What kinetic and thermodynamic characteristics are established in a melt of hydrogen-reduced iron ore pellets? The pellets contain self-fluxing slag components which upon melting form an initial slag. Refining capabilities of this slag, such as dephosphorization power, are investigated in a lab-scale vertical furnace. READ MORE

  5. 5. Experimental testing of adsorbents for H2S removal in industrial applications : A comparative study on lifetime and cost effectiveness of different materials

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Fanny Boström; [2019]
    Keywords : ;

    Abstract : Harmful emissions are a global issue and cause trouble for human health and for the environment. There is a wide variety of pollutants and one pollutant is hydrogen sulfide, H2S, that is a member of the group Volatile Sulfur Compounds. READ MORE
